i RAIL- CHAIR.

Specification of Letters Patent.

Patented Aug. 3, 1920.

Application filed March 15, 1920. Serial No. 365,967.

To all whomct may concern:

Be it known that I, NAZZARENO GIACOMELLI, a subject of the King of GreatBritain, residing at Newburgh, in the State of New York, United Statesof America, have invented certain new and useful Improvements inRail-Chairs; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enable otherskilled in the art to which it appcrtains to make and use the same.

The present invention has relation to rail chairs for railway rails andthe principal object is to provide a device, adapted for cushioning therails and for equalizing the stress encountered thereby.

Another object of the invention is to provide a deviceby the use ofwhich the ordinary tie joining attachments are dispensed with.

A further objectfis to provide a device by the use of which the life ofthe rail tie is prolonged.

Withthe above and other objects in view which will hereinafter appear asthe de scription continues, the invention consists of the novel featuresof construction, combination and formation of parts as will behereinafter more fully described and particularly pointed out in theappended claims.

In the accompanying drawings has been shown a simple and preferred formof the invention, it being, however, understood that no limitation isnecessarily made to the precise structural details herein exhibited, butthe right is hereby reserved to any changes, alterations ormodifications to which recourse may be had that come within the scope ofthe claims without departing from the spirit of the invention orsacrificing the efiiciency of the same.

In the accompanying drawings:

Figure 1 is a perspective view of the improved rail chair, detached fromthe tie;

Fig. 2 is a detail sectional view of the device, illustrating theattachment of the same to the rail and tie; V

Fig. 3 is a fragmental perspective view of the truss plate; and

Fig. 4 is a perspective view of one of the spring plates.

Referring to the figures by numerals ofreference, 10 designates therailway tie of ordinary wooden construction, but which may likewise beof metallic construction.

A base plate 11 is attached to the tie 10 by the spikes 12, which passthrough the openings 13 at each end of the base plate.

The base plate 11 is of rectangular configuration and is preferably castout of malleable steel of requisite toughness and said plate, adjacentits opposite ends, is formed with offsets 14 and 15, which latter areprovided with angularly disposed channels 16 and 17.

Mounted on the base plate 11 and having its opposite ends 18 and 19disposed in the channels 16 and 17 is the truss plate 20, constructed ofspring steel metal. This plate 20 is formed with angularly disposed legportions 21 and 22 which are joined at the central partby the flathorizontal portion 23. Theflat horizontal portion 23 is formed with aseat 24 adapted for the reception of the base 25 of the rail 26. The legportions 21 and 22, adjacent their connection with the flat portion 23,are formed with the bolt openings 27 and plates 28 and 29 are connectedby bolts 30, to the upper ends of the angular leg portions 21 and 22.The bolts 30' pass through the openings in the plates 28 and 29, and theopenings 27 in the truss plate 20, and nuts 31, when adjusted, hold theplates 28 and 29 in position thereon. The ends of plates 28 and 29extend over the rail flanges 32 and preferably contact with the fishplates 33 and 34 which unite the confronting rail ends by meansof thebolts 35 in the usual manner.

Attached to the base plate 11 at its central part by means of the bolts36 are the spring plates 37, 38 and 39 which are formed with fiatportions 40 and tapered upwardly inclined end portions 41 and 42, theextreme outer ends of which being bent over in tubular configuration asat 43. The lower spring plate 37 has its flat portion 40 engaging theupper surface of the base plate 11, and its tapered portions 41 and 42are disposed at a moderate angle. The angle of the tapered portions 41and 42 of the spring plate 38 is more abrupt than that of the taperedend portions of the spring plate 37 on the flat portion of which it ismounted. The spring plate 39 is nested upon the plate 38 and has itstapered end portions 41 and 42 pitched at a more abrupt anglethan thatof the ends of plate 38.

The truss plate 20, on the under surface of the inclined end portions 18and 19 thereof, is provided with the spaced apart longitudinal ribs 44and 45 which are apertured at 46. These ribs 44 and 45 are spaced apartat such distance to permit of the insertion therebetween ofthe tubularends 43 of the spring plates 37, 38 and 39.

Bolts 47 pass through openings 46 in the ribs 44 and 45 and likewisethrough the tubular end portions43 of the sprin plates 37, 38 and 39, bymeans of which tiey are connected to the truss plate 20.

In this manner, the spring plates 37 38 and 39 are nested together onthe base plate 11 by the bolts 36 and nuts 48, and their end portionshave bearings upon the bolts 47 of the ribs 44 and 45 of the truss plate20. By positioning the truss plate 20 in such manner that its oppositeends 18 and 19, only project partly into the channels 14 of the baseplate 11, the same is capable of longitudinal adjustment due to theweight of the train and to the stress encountered. This adjustment andstress are regulated by the spring plates 37, 38 and 39, the inclinedends 41 and 42 of which are adapted to be tensioned downwardly. Thediminution of theangulation of the ends 41 and 42 of the spring platesvaries in ratio to the weight of the train upon rails 26, and the stressin consequence of the travel of the train thereover. The greater thestress encountered, the greater will be the reduction of the angularlydisposed plate ends 41 and 42.

As the upper spring plate 39 receives the dimet force of the weight andstress, its ends are pitched at a more abrupt angle than the ends ofplate 38 and consequently spring plate 38 has its ends pitched upwardlyat a more abrupt angle than the ends of spring plate 37.

As the plate 20 is constructed of spring steel, the same is capable oflimited resiliency, and the movement in longitudinal continuity of itsends 18 and 19 is limited in channels 16 and 17 in the offsets 14 of thebase plate 11.

It will thus be seen that the stress encountered by the rails will beimparted to the truss plate20 and the spring plates 37, 38 and 39 andwill thus be equalized.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. A rail chair comprising. a'base plate,

said plate adapted for connection to a tie,

said plate adapted for connection to a tie,

a truss member adjustably connected to the base plate, a plurality ofspring plates interposed between the truss member and base plate, andmeans for connecting the spring plates to said base plate and the trussmember. 7 7

In witness where'ofI have hereunto set my hand. v
